One of the earliest dilemmas any new Apple Watch owner faces takes place even before the purchase has been made—the gargantuan task of figuring out which size wristband or strap suits your wrist best.

It might not seem like a big deal, but you’re going to want your brand new Apple Watch to fit just right in order to record accurate data for fitness and sleep tracking. Plus, wearing a watch that doesn’t fit right just makes the user experience feel janky.

It seems Apple is definitely aware of this problem, evident with a recently won patent for what’s being dubbed an in-store Apple Watch Touchless Wrist Measurement System to help people get the right fit.

No more guessing

Choosing the right band size for your Apple Watch is an often overlooked step in the purchasing process. It gets even more difficult and cumbersome if you’re eyeing something like Apple’s Solo Loop, which doesn’t feature any buckles, clasps, or overlapping parts. This makes the size somewhat bespoke to the user (given a very narrow size range for each Solo Loop).

But with Apple’s Touchless Wrist Measurement System, all you’ll need to do is pose your wrist in different positions above a sensor. This sensor will then process the right size for you. It’s a pretty novel idea, and it makes you wonder why something like this hasn’t already been put to work in Apple stores.

This leads us onto the next exciting development.

If you take a close look at Figure 1 above, the proposed Depth Sensor is being used in tandem with an iPad or iPhone, which could signal plans for Apple to implement this feature on future consumer products, so we can do the fitting ourselves at home.

Of course, we’re just guessing here. It usually takes many years for a patent to result with a tangible product we can buy. And with something this advanced, we can’t expect it (or anything remotely related) to come any time soon.

But then again, Apple’s native Measure app already does a pretty good job with its augmented reality (AR) measuring tools. Perhaps the new Wrist Measurement System will use some iteration of this app. Again, we’re just guessing!

For now, we’re still stuck with the paper cutout that Apple makes you print in order to get accurate wrist measurements.
